Improved design revealed for $620m Darlington Upgrade on Adelaide's North-South Corridor

AN improved design for the $620 million Darlington Upgrade on the North-South Corridor was this week unveiled and released for public consultation by Australian and South Australian governments.

The alternative design will now allow thousands of motorists who use Flagstaff Hill Road and Main South Road every day the ability to use the non-stop motorway to avoid three sets of traffic lights.

The previous scheme only provided motorists using the Southern Expressway the ability to access the new section of road.

The Darlington Upgrade design also has a lowered road that passes underneath Flinders Drive and Sturt Road, and an interchange at the junction of the Southern Expressway and Main South Road.

There is better access to the Flinders Medical Centre, Flinders University, Tonsley precinct and other local businesses, while Main South Road/Ayliffes Road intersection is unchanged.

Federal Assistant Minister for Infrastructure and Regional Development Jamie Briggs said the announcement was an important step for the $620 million Commonwealth and State funded project.

"This is another example of the Australian and State Governments building for our future to create jobs and grow the South Australian economy so everyone can prosper," Mr Briggs said.

"This project is an investment in South Australian jobs and economic growth. It will support about 370 jobs a year during construction, slash travel times for motorists and boost freight efficiency.

"The Darlington Upgrade will help eliminate congestion by creating a non-stop motorway along the busy 2.3 kilometre section of Main South Road between the Southern Expressway and Ayliffes Road."

The South Australian Transport and Infrastructure Minister Stephen Mullighan said the changes would add to the concept which was informed in part by public feedback.

"We know about half of the traffic coming in to Darlington from the south arrives on the Southern Expressway and the other half comes from Main South and Flagstaff roads.

"Making the non-stop motorway accessible to all of these roads means more road users will enjoy the benefits of this substantive project.

"This project will be conducted in line with the State Government's Industry Participation Policy, which seeks to give local small-to-medium businesses a better chance of being involved."

Early works are due to begin mid-year, with major construction starting late 2015 and completion expected by the end of 2018.
